Parameter Details1212.10 n: Special AdjustmentYASKAWA SIEPC71061753A GA500 Technical Manual 7270 : Feedback Method1 : Feedforward Method■ n8-88: Vout Limit Switching LevelNo.(Hex.) Name Description Default(Range)n8-88(02BD)Vout Limit Switching LevelSets the current level at which output voltage limit sequence selection occurs as a percentagewhere the motor rated current is 100%. Normally there is no need to change this setting.400%(0 - 400%)■ n8-89: Vout Limit Switching HysteresisNo.(Hex.) Name Description Default(Range)n8-89(02BE)Vout Limit SwitchingHysteresis Sets the hysteresis width of the current level at which output voltage limit sequence selectionoccurs as a percentage where the motor rated current is 100%. Normally there is no need tochange this setting.3%(0 - 400%)■ n8-90: Output Control Speed SelectionNo.(Hex.) Name Description Default(Range)n8-90(02BF)Vout Limit Switching SpeedSets the speed level at which output voltage limit sequence selection occurs as a percentage wherethe maximum output frequency is 100%. Usually it is not necessary to change this setting.200%(0 - 200%)■ n8-91: Id Limit at Voltage SaturationNo.(Hex.) Name Description Default(Range)n8-91(02F7)Id Limit at VoltageSaturation Sets the limit value of feedback output voltage limit Id operation. Enabled when n8-87 = 0[Output Voltage Control Selection = Speed Feedback Form]. Usually it is not necessary to changethis setting.-50%(-200 - 0%)■ n8-94: Flux Position Estimation MethodNo.(Hex.) Name Description Default(Range)n8-94(012D)ExpertFlux Position EstimationMethod Sets the criteria that the drive uses to find changes in speed or load. Usually it is not necessary tochange this setting.1(0, 1)0 : Softstarter1 : Speed FeedbackSet n8-57 = 1 [HFI Overlap Selection = Enabled] to enable this parameter. Increases the stability when the speedor load suddenly change, for example with rapid acceleration/deceleration or impact loads.■ n8-95: Flux Position Est Filter TimeNo.(Hex.) Name Description Default(Range)n8-95(012E)ExpertFlux Position Est FilterTime Sets the time constant of the filter used for the recognition criteria value for speed and loadchanges. Usually it is not necessary to change this setting.30 ms(0 - 100 ms)Note:Enabled when n8-94 = 1 [Flux Position Estimation Method = Speed Feedback].◆ nA: PM Motor Control TuningnA parameters make adjustments for controlling PM motors.V/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLV
